**app.Execute(code)** This method executes a code in a similar way as eval() but it returns undefined. app.Execute("app.ShowPopup('Hello')") // shows a popup app.Execute("app.Exit()") //exits app. The main use of app.Execute is to call DroidScript code from within html. This can be within an html app or a WebView. For a sample, take a look at [[sample_code:using_app.execute|this sample]]
